I watched a movie or show (NOT DOCTOR WHO) on TV about statues that move (and kill) only when not looking at them. I'm 90% certain it was a Sci-Fi channel show (before the name change). I would have to say I first watched the movie over 10 years ago.
The statues were human sized, possibly angels, or gargoyles or something, I don't remember. They did not show them moving, but they did did show changed positions and poses (arms out, mouths open). Not bushes, and I don't think they were controlled but I don't know- I didn't see the end of the movie.
I know there was a Dr. Who episode “Blink” featuring similar beings, not asking about that.
